| 摘 要： | 为了满足某些特殊通信服务在跨服务器认证密钥交换时必须由客户直接协商产生会话密钥的要求,该文提出一种新的基于口令的跨服务器认证密钥交换协议。该协议对在线字典攻击的反应灵敏度及发现此类攻击的计算代价和通信代价低;分析结果表明,新协议满足基于口令的认证密钥交换协议的安全性要求。

| Abstract: | In order to meet the special requirement in some special communication servers that the session key needs to be generated directly by the clients themselves who are located in distinct authentication servers,a novel password authenticated key exchange protocol is proposed in this paper.The new protocol is more sensitive to the online password guessing attacks with less computing and communication.The analysis shows that the new protocol meets the security requirements of password authenticated key exchange protocols. |
